The older mickey d units were model 8634 and the wendys frosty units are 358

Nicklehead- not sure of the numbers but have worked on many different machines. Wendy's new style and old style frostys, DQ, Tastee Freeze, and a couple of Mickey D"s as well as many at the road side ice cream shop.

The overrun is the amount of air whipped into the mix and is controlled by the tube that is inserted into the hopper drain, small hole in that tube goes down. Usually the temperature of the product in the barrel is controlled by the setting of the constant pressure valve. I hope this helps, soft serv machines can be a pain. The machine you are working on may use a barrel temp control, or a solid state temp control and a temp probe. If you want a real challenge, try a Mickey D's soft serv machine.

what kind of experience do you have with the models 358 and the 8634?

I am not sure what the pressure should be on 409A I dont have much expierance with it but when I checked the chart I am going on memory here it has been a while I think the temp was -15 according to pressure. I would like to investigate a different refrigerant for this compressor I will have to look it up. Do you think bearings have anything to do with this I am not sure as both sides are doing the same thing. Thanks Paul

on your 409A set your psi to 10psi for the hopper system

the metal scraper blades do last longer but the plastic scraper blades are alot safer

when you order a tune up kit from your local distributer it doesnt come with the scraper blades those are extra

I'd check what overrun they have the machine set for and also check the density setting potentiometer.

Hi Thanks for the reply! I am still green when it comes to taylor machines I did tell my customer that I knew nothing about this machine but that I would take on the challenge if he would be willing to be patient, he agreed and he has been very patient I did find out from an employee of his that he has had four other guys out to fix this machine and I am the only one that could get it to make ice cream. My question to your reply is did you have to change cap tube when you used 414 in hopper compressor? How do you check overun? And what is a Potentiometer and how do you check and adjust this? Thanks again paul

and also did your pressures seem wierd on the hopper system

When R-409 was first introduced, it was advertised as a drop in replacement for R-12, later they found that the cap tube wouldn't work, and recommended it be replaced with a longer one. Take the compressor hp and cross reference it on a Supco cap tube chart, as the factory isn't going to have any recommendations.

Yes the hopper used to be r-12 but it has a new compressor with 409A in it, I am not sure if the tech that replaced this compressor changed the cap tube or not I will take your advice and check this out. Thanks Paul

The model number is 8334 serial number to follow this info is in the service van. I will post it wednesday Thanks Paul

Their web site doesnt support this model anymore I asked because you said you just did one thought maybe you would have some insight on the prceedure. Thanks paul

Okay can you tell me what all is involved in doing this?

I just fix one last week.
Problem is the gear box worned -out.
And I have to replace the bearing kit and lubrication.
Have you replace the bearing kit every half year?

Hi I am working on a 30 year old two head machine this unit should be in the graveyard. It has 409A in hopper compressor, 408A on one side and 134A on the other side. The complaint was ice cream not coming out fast enough and product spoiling in hopper. I think the ice cream problem can be solved my using metal scrapers instead of plastic and correct me if I am wrong. The ice cream temp is 19 degress. The hopper refrigerator is working good but I do get temp difference from the front to back 37 degrees in front and over 50 in back can this be a bearing problem on the auger? Next question is can this problem be solved? Thanks Paul
